Each frame displayed is just like a normal texture and client will resize always follow rule of 2. Have a look at Keefs link.

With animating clothing I find two frames 256x256 is what looks best smaller and you lose detail too much, 2 frames is not much of an animation though and more like on off.

another tip before you start any clothing animation, tick the scroll box and check the texture can scroll, if it can do that.. then you can animate it, few times I have made the animated texture, wasted an hour.. then finally worked out the texture slot could not be animated to start with._________________
